Mary Tyler Moore died Wednesday at the age of 80 years old, according to her longtime representative Mara Buxbaum. Actress Mary Tyler Moore is in "grave condition," TMZ wrote in an exclusive report Wednesday. The star's family rushed to the hospital to say goodbye to the 80-year-old. Moore was "critical" and "suffering from a number of health problems," the publication added. While Moore's current state was "grim," her specific ailment was unknown.

Rehearsals for the pilot episode of "Bewitched" began on November 22, 1963 -- just hours before the assassination of President John F. Kennedy. The tragedy was particularly difficult for the show's star, Elizabeth Montgomery (Samantha Stephens), and her husband, the show's producer, Bill Asher. "They were friends with JFK," Herbie J. Pilato, author of "Twitch Upon A Star" and other books about classic television told Fox News. "Asher produced Kennedy's birthday bash where Marilyn Monroe sang'Happy Birthday, Mr. President.' It was a very hard time for everybody."
